I have set up Eclipse to compile for the Arduino Due using all the tools shipped with the Arduino IDE 1.5.6-r2. It compiles without errors, but when uploaded, the Arduino does nothing, and isn't recognized on the computer. It then has to be reset manually using the erase and reset buttons.

There is one static library (ArduinoDueCore) consisting of the Arduino library (core), and other code (Atmel found in lib). The other Eclipse project is the TestProject. It contains one file blinking an LED on pin 13. All the files from the Arduino library are there.

This is the output from Eclipse compiling the library itself: (excerpt of only one of each type of command)

  • Can you tell if it works when you build and upload the program from Arduino IDE instead of Eclipse? – jfpoilpret Apr 20 '14 at 7:23
  • @jfpoilpret It works from the Arduino IDE. – Friend of Kim Apr 20 '14 at 10:19
  • Only the #include "Arduino.h" line is unnecessary. – Friend of Kim Apr 20 '14 at 10:20
  • How did you setup eclipse for Arduino, do you use eclipse.baeyens.it plugin? – jfpoilpret Apr 20 '14 at 21:02

    It is not mentioned; the latest mentioned supported IDE is 1.5.5; I guess that does not mean it won't work with 1.5.6, but you'll have to check it by yourself I think. – jfpoilpret Apr 21 '14 at 10:06

Using 1.5.6-r2 with Eclipse cause the Due to hung in Default_Handler function after entering main and polling a few times for the next SysTick gettin passed.

Some weak symbol declarations are done twice (i.e. the SysTick_Handler function definitions). They appear to overwrite each others weak alias depending on the link time usage of the objects. All declarations (not only the failing SysTick_Hanlder) from cortex_handler.c are getting overwritten by weak symbol redeclaration inside startup_sam3xa.c.

This commit seems to already address a weak symbol definition problem. https://github.com/arduino/Arduino/commit/65f00a69c74ca0def8d7f1d7597327945a04a33f

For now, to fix it. Just comment out the part in startup_sam3xa.c with the weak symbol declaration regarding the vectors. Lines 53 to 129.

It should also work to just remove the file completely. The startup handler code and vector map should be provided by gcc arm built-in libraries instead.
